CEMENT-POST FASTENING.

Specification of Letters Patent.

To aZZ whom it may concern.-

Be it known that I, HENRY MOMASTER, a citizen of the United States,residing at Detroit, in the county .of Wayne and State of Michigan, haveinvented certain new anduseful Improvements in Cement-Fence-PostFastenings, of which the following is a specification.

This invention relates to a fastening to be used in connection with acement or other fence-post, and has for its object to provide a means ofattaching wires to the post in such a manner that they can be readilyremoved without injury to the fastening and the fence.

It is the further object of this invention to provide a system ofreinforcement in connection with the fastenings and to make them in sucha form that they can be readily placed in proper position in themanufacture of the post.

It is a further object of the invention to make these fastenings. insuch a manner that the wires will be securely held at these points andwill not be movable in the fastenings. These I attain by the novelconstruction and combination of parts hereinafter more fully describedand claimed.

In the annexed drawings, constituting a part of this specification,Figure 1 is a perspective view of a post, showing the fastenings andmethod of securing the wires there- Fig. 2 is a view of one modificationof my fastening-clip. Fig. 8 is a sectional view of the clip, showingthe wire kinked and held in position by the pin. Fig. 4 is a view ofthese fastenings in combination with metal reinforcement. Fig. 5 is amodified form of myfastening-clip and is adapted to be used inconnection with wood or other posts.

The gist of the invention consists in roviding a slotted recess for therece tion 0 the fence-wires and of having shoul ers on the innerextremities of the slot at such a point that the wire is kinked when thepin-fastening is inserted. In this manner a positive attachment is madeat each post, so that the strain of the fence is evenly distributed andis not transmitted to the end posts.

Similar letters refer to like parts throughout the different views.

A is the body of the post, which referably would be made of concrete,thoug may be made of anyv other material, such as wood, especially whenthe modified form of the fastening is used.

B is a metal clip which consists of a looped portion which isprovidedwith the slot C. The exterior ends of this metal clip in onemodification of my invention are provided with the hooks D to form abetter contact with the post when a cementitious material is used.

E represents the pins which hold the wires F in position. As moreparticularly shown in Fig. 3, the wire F when placed in the slot 0strikes against the inward shoulders and will be kinked either bystriking with a punch or by inserting the pointed end of the pin E anddriving it in position. It will be observed that the slot C should notextend in as far as the shanks of the clip B, but instead should form aslot somewhat less than the combined width of the wire and the diameterof the pin.

A modified form of my invention is shown in Fig. 4, in which Grepresents a number of longitudinal reinforcing members, at the up- %erend of which is attached one of the clips Near the lower end is alsoattached a second clip B by riveting or other suitable means. Thesewould be arranged so as to register with the upper and lower wires ofthe fence. Any desired number of additional clips B can be placed atproper intervals to receive and hold the other wires of the fence.

One of the reinforcements G may be extended upward and turned uponitself to form a clip for the top fence-wire. In this way the metalreinforcement for the post can be constructed so that it can be easilyhandled and readily inserted in the post in the proper position.

The reinforcements .G may extend the entire length of the post or, ifpreferred, may terminate at their lower extremities a short distancebeyond the ground-line. In this case I would insert additionalreinforcements H, overlapping the lower extremities G and forming at theground-line, where there is the greatest stress, the double amount ofreinforcement. The adhesion of concrete to steel being several hundredpounds to the square inch will make a sufficient union between the metaland the concrete, so that any method of fastening the lowerreinforcements to the upper section will not be necessary. If preferred,the intermediate clips B may be hooked to one of the strips G and byspring-pressure against one of the strips G be held in position whilethe post is being made. This arrangement is especially advantageous andfacilitates the work greatly over having the clips separate and loose.

If desired, the modification of the clip as shown in Fig. 5 can be usedin a wood post or in a cement post containinga wooden strip. Preferablywhere the clip is intended for a wood post the edges of the shanks wouldbe barbed, so that they would not easily be Withdrawn from Wood. Aftertlf pos-s ave been made with the clips properly spaced .tl e

fence is stretched in position and the WlI S inserted in the slots C.The pins E may be or linary Wire nails or any convenient slaped piece ofmetal, so that they can be driven in position and withdrawn when it isdesired to remove the fence.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. 'lhe combination with the cementitious body material of a fence-post,of a plurality of fastenings consisting of sections of metallic bandsbent upon themselves and having their inner ends hooked, of slots in theopposite ends, of shoulders on the inner portion of the slotsterminating outside of the cementitious body against which thefence-wires are kinked by means of the fastening-pins, substantially asdescribed.

2. In a concrete fence-post the combina- 0 tion with the cementitiousbody material, of a plurality of flattened key-shaped metal portionshaving inwardly-projecting slots at their outer or bent ends, theopposite ends of the key-s .aped metal portions being hooked, tl e soulders at the inner portion of said slo s disposel outside of the faceof the post, of pins in front of the wires inserted in said slots ofsufficient diameter to kink said wires, sub- HENRY MCMASTER.
